Elysium Mons Caldera
PSP_004903_2050  Science Theme: Volcanic Processes

PSP_004903_2050 captures the full western margin of the Elysium Mons caldera. A caldera is a feature that forms by the collapse of land after a volcanic eruption. This caldera is approximately 14 kilometers in diameter.

Several pit crater chains can be observed radiating out from the caldera. These likely formed due to surface collapse from igneous dike intrusions and/or normal faulting. Some are very clear and pronounced, such as the one to the north of the caldera, and others are fainter, such as the ones at the bottom of the image, suggesting the lower ones have been subsequently covered by sediments, dust, or lava flows.Written by: Alix Davatzes   (31 August 2007)
